To all whom it may concern:

Be it known that I, GEORGE BENTOTE, lam -works manager, a subject of the King of reat Britain, residing at 17 Shaa road, Acton, in the county of Middlesex, England, have invented certain new and useful Imrovernents in or Connected with Lamps for urning Oil or Spirit, of which the following is aspecification, reference being had to the drawings hereunto annexed, and to the letters marks thereon.

The invention relates to im rovements in or connected with lamps for hurning oil or spirit; and the primer ob'ect thereof is to provide a lamp adapts to t into the tube or socket of an ordina carriage lamp or lantern similarly to an in lieu of the ordinary candle and to burn benzolin in such manner that a flame capable of regulation and of considerable illuminating power is obtained without the employment of a chimney and without the necessity for attention after first lighting.

In the accompanying drawings, Fi ure 1 is a sectional side view of a carriage lamp or lantern fitted with a benzolin-lamp according to the present invention. Fig. 2 is a side elevation of the lamp separately. Fig. 3 is a plan thereof. Fig. 4 1s a vertical section taken on the line 1 1 of Fig. 3. Fig. 5 represents part of Fig. 4 drawn to an enlarged scale. Fig. 6 is a vertical section taken on the line 1 1 of Fig. 3 of the cap and burnercone of the tubular reservoir separately. Fig. 7 is a similar view of the cap of the perforate chamber separately. Fig. 8 is a similar view of the wick-tube separately. Fig. 9 is a sectional elevation of part of a carnagedantern with the lamp in position ,illustrating a modification. Fig. 10 is a similar view to Fig. 5, but illustrating the employment of a wick tube fixed with the cap of the perforate chamber; and Fig. 11 is a similar view to Fig. 5, but showing the wick-tube and wick dispensed with.

In the several figures like parts are indicated by similar letters of reference, and Figs 2 to 4 and 6 to 11 are drawn to an increased scale, and Fig. 5 is drawn to a further increased scale with respect to Fig. 1.

Referring to Figs. 1 to 8, c represents an ordinary carriage lamp or lantern, which is constructed with the usual candle tube or socket a, cap or cone a fastened by the usual bayonet-catch, and internal spring a". b represents a tubular reservoir, which is closed at the bottom but open at the top and of similar diameter and length to an ordinary carriage-candle, so that it is ada ted to fit into the tube or socket a of an or inary carriage lamp a, and this reservoir is designed to be partially filled with benzolin. Loosely fitting the reservoir and coextensive in length therewith is a perforate tube, cylinder, or chamber 0, closed at its lower end and adapted tobe filled with cotton-wool 0 cottonwaste, s onge, or other suitable material, preferab r of a springy or s ongy nature, which takes up the free benzo in within the reservoir 5. The perforate tube or chamber a is at its top end closed by a cap 0, having a conical top axially perforated and formed with a flange 0 around the perforation constituting a short tubular fitting, in which is mounted with ca ability of sliding for adjustment of the wic a wick-tube c fitted with an asbestos or other suitable incombustible wick c of such a length that it extends into the body of the saturated absorbent material c, or it might lie upon the surface thereof.

The top end of the reservoir 1') is closed by a cap consisting of a cylindrical part 5 having a conical top shaped somewhat like the top end of an unburned candle and axially perforated and formed with a shallow flan e b, similarly to the cap 0' of the perforate 0 amher 0; but in this case the perforation is of considerably larger diameter than the wicktube 0 so as to leave an annular space between the flan e b of the cone 1) and the wick-tube c 11 order that the height of the flange b of the cone b with relation to the wick-tube 0 may be regulated, the reservoir 1) is provided with a laterally-projectin pin or stud b and the cylindrical part b o the cap of the reservoir 1; is formed with a coacting circumferential and inclined or spirallydisposed slot 5, terminating in a vertical opening after the manner of a bayonet-fastening, so that by turning the cap 6 in one or the other direction the height of the cone b and its flange b may be adjusted within certain limits and the height of the flame correspondingly regulated, and in order to pre vent the accidental shifting of the cone, due to vibration or other cause, the metal bordering the top edge of the slot 1) is provided with a series of notches or indentations which en age the pin b i desired, any other suitable means than the slot 3) and pin b may be employed for regulating the burner-cone b.

The operation of the lamp may be described as follows: The perforate chamber 0 is removed from the reservoir b by taking oll the cap 5 and the reservoir is filled to a suitable extent with benzolin. The perforate chamber is then introduced into the reservoir b, when the material 0 absorbs the free benzolin. The benzolin is lighted at the wick c, which projects slightly above the wicktube 0 and the height of the wick is re rulated by more or less elevating or de 7 ressing the sliding wick-tube c by the aid of the notch 0 The cap I) of the reservoir is then replaced in position and the cone 1) is suitably adjusted with relation to the wick-tube a The cone b has the effect of spreading the flame while a small volume of gas or vaor finds its way between the perforate chamer c and the reservoir 1) and between the flange b of the cone 1) and the wick-tube 0 thereby to some extent feeding and aug mentin the flame the volume of which may be regu ated in the desired manner by means of the adjustable cone 1). The lamp is then bodily introduced into the tube or socket a of the lantern a against the force of the sprin r a? after the manner of a candle and secure by the cap a In the example given at Fig. 9 the lamp b is assumed to be identical in construction with that hereinbefore shown and described; but the lantern a is modifiedthat is to say, the spring a is dispensed withthe socket a is shortened so as to nearlyfit the lamp 1), and the bottom end of the lamp 1) is provided with several buffer-springs I), radiating from a central disk or boss I) and which lightly press against the wall of the socket a and serve to prevent the independent vibration of the amp I).

In the example given at Fig. 10 the lamp is of precisely similar construction to that described with respect to the previous figures, except that the wick-tube c is fixed with the cap 0 of the perforate chamber a and the adjustment of the wick c is effected by pricking it up or down in the well-known manner.

11 the exam le given at Fig. 11 the device is further mo ified by dispensing with the wick-tube c and wick 0; but a small body of asbestos 0 is placed on the top of the absorbent material a and is adapted to be pricked up into the perforation of the cap 0' to fulfil the function of a wick.

The cost of burning a lamp of this character is extremely low compared with that of candles, the illuminating power of the flame is greater than that of a candle of equal size, while by reason of the indestructible nature of the wick the trimming of the lamp is of a mostsim le character, the char ing of the reservoir eing all that is re uirecI, so that in this res ect also it compares avorably with a candleam It will be obvious that the invention is not necessarily confined to carriagelam s, but may also be applied to other kinds o 3 lamps employed for various purposes and to dwarflamps o1 night-lamps.

Having now particularly described and ascertained. the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a lamp, a reservoir, a perforate chamber fitting within the reservoir and adapted to be filled with absorbent material, a conical centrall -perforated cap closing the top of the perforate chamber and a centrally-perforated conical cap or burner-cone closing the top of the reservoir and inclosing the cap of the perforate chamber but formed of larger dimensions than the latter cap so as to leave a passage between the two caps substantially as herein shown and described and for the purpose stated.

2. In a lamp, a reservoir, aperforate chamber removably fitting within the reservoir and adapted to be filled with absorbent material, a conical centrally-perforated cap closing the top of the perforate chamber, a centrally-perforated conical cap or burner-cone closing the top of the reservoir and inclosing the cap of the perforate chamber but formed of larger dimensions than the latter cap so as to leave a passage between the two caps and means for varying the elevation of the burnercone substantially as herein shown and described and for the purpose stated.

3. In a lam a reservoir, a perforate chamber reinovablg fitting within the reservoir and adapted to be filled with absorbent material, a centrally-perforated cap closing the top of the perforate chamber, a wick-tube fitted within said perforation and adapted to hold a wick, a conical cap or burner-cone closing the top of the reservoir and inclosing the cap of the perforate chamber and centrally perforated with a hole of larger diameter than the Wick-tube said cap or cone bein formed of larger dimensions than the cap 0 the perforate chamber so as to leave a passage between the two caps and means for varyin the elevation of the burner-cone substantia ly as herein shown and described and for the purpose stated.

4. In a lamp, a reservoir, a perforate chamber removably fittin within the reservoir and adapted to be fil ed with absorbent material, a centrally-perforated cap closing the top of the perforate chamber and ada ted to be fitted with a wick, a conical cap or urnercone closing the to of the reservoir and inclosing the cap of the perforate chamber and centrally perforated and formed of larger dimensions than the cap of the perforate chamber so as to leave a passage between the two caps, a pin upon the reservoir and an inclined slot in the burner-ca or cone engagi said pin substantially as erein shown an described and for the purpose stated.

5. In a lamp, a reservoir, a perforate chamber removably fitted Within the reservoir and adapted to be filled with absorbent material, a centrally-perforated cap closing the to of the erforate chamber, a wick-tube ad iustably tted within said perforation and adapted to hold a Wick, a conical cap or burner-cone closing the top of the reservoir and ineiosing the cap of the perforate chamber and centrally perforated with a hole of larger diameter than the Wick-tube said cap or cone being formed of larger dimensions than the cap of the perforate chamber so as to leave a passage between the two caps and means for varyin the elevation of the burnercone substantial y as herein shown and clescribed and for the purpose stated.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
